Pigmented Skin Lesions

Various structures have been reported for dermoscopic features of pigmented Bowen's disease (BD), which could be a mimic of various pigmented skin lesions. A 79-year-old Japanese woman presented with a 3-year history of brown-black macule on her right upper arm without symptom. Dermoscopic examination demonstrated irregular flossy streaks, irregular brown dots/globules, blue-whitish regression structures, and overlaying whitish scaly areas. We suspected pigmented skin lesions including seborrheic keratosis, pigmented eccrine poroma, and malignant melanoma and excised completely with a 5 mm margin. Histopathological features were consistent with a diagnosis of pigmented BD. Although similar dermoscopic features might be revealed in pigmented skin lesions and it may occasionally be difficult to distinguish between pigmented BD and other pigmented skin lesions, dermoscopy would be useful in speculating pathologic features of pigmented BD.

Clinical Differential Diagnosis

Circumscribed palmoplantar hypokeratosis is a recently recognized dermatosis and rarely reported. It was first described in 2002 and is characterized by localized loss of the horny layer in the palmoplantar area. This dermatosis is clinically presented with a sharply circumscribed, reddish and asymptomatic plaque with slightly depressed surface localized on the palms or the soles. The clinical differential diagnosis includes mainly porokeratosis and Bowen's disease. Its pathogenesis remains unknown, but studies have proposed a human papillomavirus induced disease or a localized keratinization disorder in the palmoplantar area. We report herein two cases of patients with lesions clinically and microscopically compatible with the diagnosis of circumscribed palmoplantar hypokeratosis. We also present a brief literature review of the etiopathogenic hyphoteses of this dermatosis.

The main objective of surface microscopy is the early and accurate diagnosis of melanoma in its initial phases of evolution and infiltration. Since the development of the dermatoscope in the 1990's, surface microscopy has become a simple technique. Differential diagnosis of pigmented skin lesions can be achieved with a diagnostic sensitivity of about 90 percent, and the proper differentiation of pigmented melanocytic and non-melanocytic lesions, and malignant and benign melanocytic lesions, may also be safely determined.

Arsenic has been classified as a class I human carcinogen, meaning that there is sufficient evidence of carcinogenicity to humans. Arsenic, however, remains a common contaminant in a number of traditional Chinese herbal balls. A 64-year-old man presented with an erythematous erosive patch on the left palm, multiple yellowish scaly patches on the right palm and an erythematous hyperkeratotic patch with bleeding on the left foot dorsum. He also had similar skin lesions on the back and buttock. He had a past medical history of chronic exposure to arsenic through consumption of traditional Chinese herbal balls. Skin biopsy revealed Bowen's disease on the left palm and squamous cell carcinoma on left foot dorsum. We report this case to emphasize that we should investigate patient's history thoroughly, including the use of Chinese herbal balls to find out arsenicism.

Background: The diagnosis of squamous cell carcinoma (SCC) is, generally, a clinical diagnosis, but in some cases, when the lesion is pigmented, as in our case, the differential diagnosis between pigmented SCC and other pigmented skin lesions, in particular melanocytic lesions, is difficult. Dermoscopy may improve the early diagnosis of SCC and thus play a role in its preoperative classification. However, its potential role has been hampered so far by the fact that little is known about the dermoscopic features of pigmented SCC. Objective: We report the case of a rare pigmented SCC dermoscopically mimicking a melanocytic lesion whose dermoscopic features have been investigated. Conclusion: On the basis of the literature and our experience, pigmented SCC can present dermoscopic features typical of melanocytic lesions, such as radial streaks, globules, and homogeneous blue pigmentation, and can lead dermatologists to diagnostic errors.
